Create an API key, point any website form at the public submit endpoint, and optionally connect an MCP client or SDK. This page is the hub for agents and humans looking up FormsReach developer resources by name.

• OpenAPI spec

  Machine-readable Submit API with unique operationIds, typed bodies, and JSON error schemas. Built for LLM function calling.

  openapi.json

• API keys

  Create a form in the dashboard and copy the public api_key. Use a Free-plan form as the sandbox before production.

  Open dashboard

• Docs quickstart

  Paste an HTML form, submit a test, and confirm the row. Then add spam fields and a domain allowlist.

  Quickstart

• MCP server

  Streamable HTTP at app.formsreach.com/api/mcp. Public tool list on this site; live tools require a developer API key.

  MCP guides

• JSON errors

  Problem types, messages, and resolution hints at /errors/{code}. The live submit API already returns this envelope.

  Error catalog

• Rate limits

  RateLimit and Retry-After conventions so agents can self-throttle. Documented next to the Submit API.
